INTRODUCTION
Thank you for purchasing a Pioneer PB Series Self-Priming centrifugal pump, complete with
integral suction check valve. The pump is designed for handling non-volatile, non-flammable,
mild industrial corrosives, residues and slurries containing large entrained solids.
WARNING!!!
This manual provides installation, operation and maintenance instructions for your Pioneer
Self-Prime Pump and is intended to make your personnel aware of any procedure that requires
special attention because of potential hazards to personnel or equipment. Read all instructions
carefully and remember, pump installations are seldom identical. Therefore, this manual
cannot possibly provide detailed instructions and precautions for each specific application.
Thus, it is the owner/installer’s responsibility to ensure that neither operator safety nor pump
integrity are compromised by installations and applications that are not addressed in this
manual.
WARNING!!!
Centrifugal Pumps are designed for specific service and may or may not be suited for any other
service without loss of performance or potential damage to equipment/personnel. If there is
ever any doubt about suitability for a specific purpose; contact your Pioneer Pump, Inc.
representative or the factory for assistance.
Remember: Pump performance may be affected by changes in pumpage such as, specific
gravity, viscosity, temperature, operating speed and net positive suction head available
(NPSHA).
INSPECTION
The pump assembly was inspected and tested before shipment from the factory. Before
installation, inspect the pump for damage that may have occurred during shipment.
PRE-INSTALLATION INSPECTION
Check as follows: Inspect the pump for cracks, dents, damaged threads, and other obvious
damage.
Check for and tighten loose attaching hardware. Since gaskets tend to shrink after drying,
check for loose hardware at mating surfaces.
Carefully read all warnings and cautions contained in this manual or affixed to the pump, and
perform all duties indicated. Note the direction of rotation indicated on the pump and check
that the pump shaft rotates counter-clockwise when standing on the suction side of the pump
and facing the impeller.
